The ZRP zeolite modified with rare earth also possessed more strong acid,over which in cracking reaction of FCC gasoline,not only increased the conversion of olefin,but also the selectivity of propylene increased,resulting in the olefin conversion of 74.32%,the olefin mass fraction of 18.20% in cracking gasoline and the propylene selectivity of 45.91%.
To commercial feedstocks,the influence of the diene value of feed,(C_o)inlet temperature (T_o)and LHSV (S_v)on diene hydrogenation conversion and the increase of reaction temperature have been investigated via the performace study of the first stage hydrogenation reaction of cracked gasoline in an adiabatic intergral reactor filled with 8601 and PGC catalysts.
通过对裂解汽油一段加氢8601催化剂及 PGC 催化剂在绝热积分床反应器中的反应特性研究,考察了在工业原料条件下,入口双烯值 C_o、入口温度 T_o 以及液时空速 S_v 对双烯加氢率及反应温升的影响。
The deactivation reasons of the LY-8602 series catalyst in the hydrogenation of low sulfur cracked gasoline were studied by the characterization and evaluation of catalyst . The results indicated that the deactivation of the catalyst was mainly caused by the destruction of the active center phase of catalyst and the decrease of hydrogenation active center MO 4- on the surface of catalyst.
The process parameters in the design and operation of primary fractionation system in ethylene unit,such as primary fractionator bottom temperature,crack gasoline reflux quantity,quench oil recycle quantity,quench oil viscosity,crack gas oil and crack fuel oil extruct quantity,were analyzed.
APUSM technology for the production of BTX and LPG from pyrolysis gasoline using metal promoted zeolite catalyst
Phase equilibria of heavy raw pyrolysis gasoline continuous mixture using Peng-Robinson equation of state
The heavy-RPG(Raw Pyrolysis Gasoline), which is a variable mixture of mainly unsaturated C9 fractions in the cracking of petroleum naphthas, is one of the important feed materials for petroleum resins.
Limited scale extraction from steam cracker pyrolysis gasoline is also practised.
Pyrolysis gasoline which is one of the byproducts produced will be transported for sale by pipeline to a third party.
Characterization of sixty alkenes in a cat-cracked gasoline naphtha by gas chromatography
Estimation of the octane number of cat cracked gasoline when the quality of the mixed feedstock changes
Hydrodesulfurization of Selective Catalytic Cracked Gasoline
Hydrodesulfurization (HDS) reaction of catalytic cracked gasoline (CCG) on Co-Mo/γ-Al2O3 was investigated in detail to make clear the important factors for deep HDS of CCG.
Selective HDS and HDN performance of PtPd/USY was found to be superior compared to a commercial CoMo/Al2O3 (KF-756) and a new CoMo/Al2O3 being industrially applied for selective HDS of cracked gasoline.
